CANCELlNG-STAMP.

SPECIFICATION forming part of Letters Patent No. 237,068, dated January25, 1881.

Application filed October 25, 1880. (No model.)

To all whom at may concern Be it known that I, LEONARD TILTON, of

Brooklyn, in the county of Kings and State of New York, have invented anew and useful Improvement in Canceling-Stamps, of which the followingis a specification.

My improvements relate to hand-stamps for stamping letters and checks,and for similar purposes.

The object of the invention is to furnish a stamp that can be readilymanipulated to bring it to the desired position on the bed, and whichshall give a uniform pressure in stamping to insure plain marking.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of the canceling-stamp and stand, the tubular postbeing partially in section. Fig. 2 is a section, vertically, of the headthat carries the plunger, with the stamp and pad shown in elevation intheir raised position. Fig.3 is a front view of the pad-carrying arm, asseen in the depressed position of the stamp. Fig. 4 is a perspectiveview of the pad and ink-box and Fig. 5 is a horizontal section of theplunger-head on line .90 m of Fig. 2.

Similar letters of reference indicate corresponding parts.

A is the stand of the apparatus, fitted for being attached to a table orother support, on which the bed or platen a is also placed. The standconsists of a circular plate, b, formed with a central aperture andhaving undercut sides, a tubular post, 0, having a semi-spherical basethat sets within the aperture of plate 12, and a flanged collar, d,around post 0, to which'the sleeve is secured by a set-screw, a. In thesleeve cl three set-screws, d, are fitted to bear on plate b, so thatthe post 0 is thereby held in place and can be adjusted to level thestamp. In the tubular post 0 is a standard, 0, the lower end of whichrests on a steel plate, j, that is secured over the lower end of post 0,so that the standard is sustained by the post and is free to turntherein.

9 is a hub or collar secured on standard 6 by a set-screw to permitvertical adjustment.

h is a horizontal arm secured on hub g and extending at both sides ofthe hub.

'i is a right-angled arm secured to the for ward end of arm 71., so thatits upper end extends horizontally in direction from the arm h, and inthe same vertical plane, or nearly so. To the rear end of arm h is fixeda cross-piece that carries two wheels or rollers, t z, one above theother, which rollers have flanged periphcries.

k is the head carrying the stamp proper, which head is attached upon anarm, I, that is formed with, or has attached to it, a verticalextension, m, that carries a flanged wheel or roller, a, resting on thehorizontal portion of arm *5. The arm lextends between the two rollers'i t, so that said arm I and its attached parts are supported by therollersi n. Apiece, 0, attached on arm h and extending over arm 1,serves, in connection with the flanges of the rollers, to prevent sidemovement of arm I. With this construction the arm l and head k, carryingthe stamp, can turn with hub g and standard 6, and the arm l also bemoved in and out, thereby permitting the stamp to be brought over anyportion of the bed a, as required. The stamp being once properly leveledwill come squarely upon the bed at every blow, thus insuring perfectmarking and the stamp may also be used with great rapidity. The head Itis fitted with a tube, Ia, which rests by flanges on the upper end ofthe head, and through the tube 70 passes the plunger p of the stamp.

To the lower end of tube 70 a collar, q, is attached by set-screws,which collar carries the ink box and pad 1', while to the lower end ofthe plunger is fixed the clamp q for receiving the die. The plunger isprovided with a rib or feather, p, which extends within a slot in tubeis, so that the tube shall turn with the plunger, thereby permitting thedie to be turned, as required, and retaining the pad in proper relationthereto. The plunger is thus also made capable of vertical movement,and, is raised by a spiral spring fitted around it above head k.

The ink-box is carried by an arm, .9, that is adjustably connected tocollar q. The lower end of this arm is provided with a tube, 8, throughwhich passes the pivot-pin r, that has attached to one of its ends aframe, t, that is adapted for receiving the ink-box.

As shown most clearly in Fig. 3, the bottom of frame tis formed withdovetail slots that receive lugs t formed on the bottom of the ink-box.The box is to be inserted endwise, and is formed with a lug, r thatextends through a slot in the side of frame t; and a latch, t isprovided on the frame to engage with lug r, to retain the box frommoving endwise, thereby preventing disengagement of lugs t from theslots. The frame 1 is slotted at its side, or provided with a bent arm,11, forming a slot, and the die-clamp q is fitted with an adjustableplate, 1, on which a roller, w, is fitted in position for entering theslot of frame 1. When the plunger is in its upward position roller w iswithin the slot,and thereby retains the ink-box in the horizontalposition, with the pad against thedie. As the plunger descends theroller carries the ink-box and pad LEONARD TILTON.
